even if they knew your name it's still a great mystery as to who your gf could be
i'm pretty sure she isn't the only person you follow/follows you or your only friend on facebook etc
"hearing about this through facebook" as you said is an excuse to cover something up because i feel like you aren't the kind of guy to post a pic with your girl and tag her with a caption like "girlfriend appreciation post!!!!!!" so knowing your phone number isnt really going to help any of us find a girl that we don't know what she looks like or any "real" detail...
it's extremely bizzare and unsettling
